Toyota Hiace and Foton van owners - if your interior lights aren't coming on when you open the doors, or your door-open warning light on the dash is acting up, this little sensor is probably your fix. This is an aftermarket replacement door jamb switch (not genuine/OEM, but made to match factory specs). It measures about 4.5x2.7x3.9cm with a 50cm cable attached, so you've got some length to work with during installation. The plastic housing is durable, and it comes in that pink/white/black color combo that matches the original style. Installing it is pretty straightforward if you're comfortable with basic car stuff - you'll need to access your door jamb area, disconnect the old sensor, and connect this one. Always double-check fitment before buying (make sure it looks like your current broken switch!), and remember that dimensions might vary slightly since they're measured by hand. The switch itself is reliable and mounts securely to trigger your dome lights when the door opens. It's one of those small parts that makes a big difference in daily convenience. No more fumbling in a dark van because the lights don't auto-turn on! Just be patient during installation, and you'll have your interior lighting system working like new again.
